This $150 mug keeps selling out at Starbucks — here's why

• Starbucks has been selling a $150 mug from Ember Technologies, and it is flying off shelves.• The12-ounce Ember Temperature Control Mug features a sleek stainless steel inner vessel, a push-to-open lid, and a hidden temperature display.

Would you spend $150 on a coffee mug? Apparently Starbucks shoppers would, and did, as the 12-ounce Ember Temperature Control Mug is currently out of stock on the Starbucks online shop, and backordered on the company's website. It will, however, make its return in a matter of weeks.

This mug isn't like your ordinary drinkware — its technology allows you to control and maintain the temperature of your brew to the degree, and for avid coffee drinkers, it's kind of a big deal.

"When you first pour the drink in there, it's so hot it burns your mouth, then it gradually gets to the temperature you like, but it's only there for a little while before it cools even more."

The temperature of the beverage can be controlled manually with a dial at the bottom of the mug, or through the Ember app on a smartphone or smartwatch.

Through the app, you can "name" your mug, create temperature presets, and manage notifications.

For those who missed out on the high-tech drinkware, Starbucks will receive additional inventory that will roll out within the next month. The company will also restock the product on its website around the end of March.
